Method for planning implant placement, the implant comprising a first implant in a first limb and a second implant in a second limb, the first and the second implant forming an artificial structure joining the first and second limb, the method comprising the steps:
a) providing a first Iimb data set representing a first reference system in which the first limb is fixed;
b) providing a second limb data set representing a second reference system in which the second limb is fixed;
c) providing a representation of the implant for the head of the second limb in a known position in the second reference system;
d) providing relative pose data representing a plurality of different relative positions and/or orientations, referred to as relative poses, of the first and second reference system;
e) determining a data set representing a plurality of envelope points, said envelope points being generated by calculating the locations of a point of the second implant representation in the first reference system for the plurality of relative poses; and
f) placing a representation of the first implant in the first reference system by adjusting and/or matching pose of the representation of the first implant to the plurality of envelope points. |
